BRST Noether Theorem and Corner Charge Bracket
Laurent Baulieu, Tom Wetzstein, Siye Wu
We provide a proof of the BRST Noether 1.5th theorem, conjectured in [JHEP 10 (2024) 055], for a broad class of rank-1 BV theories including supergravity and 2-form gauge theories.…

BV-BRST Noether theorem
Glenn Barnich, Laurent Baulieu, Marc Henneaux +1
The BRST Noether theorem, or ``Noether's 1.5 theorem'', asserts the triviality of the BRST Noether current. We provide two proofs of this theorem that are both valid without restri…

Extended-BMS Anomalies and Flat Space Holography
Laurent Baulieu, Luca Ciambelli, Tom Wetzstein
We classify the Lagrangians and anomalies of an extended BMS field theory using BRST methods. To do so, we establish an intrinsic gauge-fixing procedure for the geometric data, whi…
